商品有机肥应用效果与施用技术研究

The Application Effect and Technologies of Commercial Organic Fertilizer

为掌握商品有机肥的应用效果和施用技术,选用"地力源"牌商品有机肥为试验肥料进行三大区两年四季稻麦生产试验,结果表明:1)各大区之间产量不尽相同,但当各自肥料用量达到较高水平时,稻麦作物均能取得较高产量;2)有机肥区有机质含量增加,孔隙度加大,容重下降;3)有机肥区的稻谷出糙率、精米率、整精米率高,垩白度小;4)有机肥区的产品产值、社会效益和生态效益明显高于其它生产区。

In order to obtain the application effect and technologies of organic manure, we have chosen the commercial organic fertilizer named ＂the fertility source＂ for rice and wheat produc- tion test in three areas in two years. The results show that there are different yields for the ma- jor areas. When the respective amount of fertilizer reaches a higher level, higher yields of rice and wheat crops can be obtained. In the organic fertilizer area, when the content of soil organic matter increases, soil porosity increases, and the bulk density drops. There are higher rough- ness, milled rice rate, and whole milled rice rate in organic fertilizer areas, and the lower chalkiness. The output and the social and ecological benefits in organic fertilizer areas are high- er than those in other production areas.
